Description

Technical Field

[0001] The utility model relates to the field of slag discharge filtering, in particular to a slag discharge filtering device. Background Art

[0002] Filtration is a common separation process in industries such as chemical, pharmaceutical, food processing and water treatment. Traditional filtration equipment usually consists of a closed container with a filter screen or filter cloth inside to capture solid particles, while the clean liquid flows out through the filter material. As the filtration process proceeds, a layer of filter cake composed of trapped solid particles will form on the filter screen, which will increase the filtration resistance, thereby affecting the filtration efficiency and output. In order to solve this problem, various slag filtration devices have been developed in the industry.

[0003] Existing slag discharge and filtering devices are mainly divided into two types: manual slag discharge and automatic slag discharge. The manual slag discharge filter needs to be shut down and the filter cake needs to be cleaned manually, which not only increases the labor intensity but also affects the production efficiency. The automatic slag discharge filter automatically removes the filter cake by setting a vibration mechanism or a scraper, realizing continuous operation and improving production efficiency. However, the existing automatic slag discharge and filtering devices still have some shortcomings.

[0004] The residue formed after cleaning the filter cake will accumulate in the filter device and affect the use of the filter device. Some devices can discharge the residue from the bottom of the filter device, but the discharge is not smooth and some liquid will be mixed with the residue. Utility Model Content

[0012] Figure 2 Shown is the layout of the drain ports on the extruder. DETAILED DESCRIPTION

[0013] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0014] like Figure 1~Figure 2 A slag discharge and filtering device shown in the figure comprises: a filter 1, a slag discharge pipe 3, an extruder 4, and a water collecting tank 15. A slag discharge port 2 is provided at the bottom of the filter 1, and the slag discharge port 2 is connected to the middle part of the slag discharge pipe 3. After the residue filtered in the filter 1 is cleaned, it can be discharged from the slag discharge port 2. At this time, the residue will contain some liquid. A slag pusher is provided at one end of the slag discharge pipe 3. The slag pusher consists of a push rod 6 and a piston 5. One end of the push rod 6 is fixed inside the slag discharge pipe 3, and the other end is connected and fixed to the center of the piston 5. The push rod 6 can be electrically controlled or hydraulically controlled. The push rod 6 drives the piston 5 to push forward, pushes the residue into the extruder 4, and then retreats to the rear side of the slag discharge port 2.

[0015] The other end of the slag discharge pipe 3 is connected to the extruder 4, and the slag pusher pushes the residue entering the slag discharge pipe 3 into the extruder 4. An opening 7 is provided on the side of the upper part of the extruder 4, and the slag discharge pipe 3 is inserted into the opening 7 and fixed. The pipe mouth of the slag discharge pipe 3 will not pass over the inner wall surface of the extruder 4 to prevent obstruction when the pressing plate 10 is pressed down. A hinged baffle 8 is provided at the end of the slag discharge pipe 3, and the upper end of the baffle 8 is hinged to the upper side of the slag discharge pipe 3. The baffle 8 naturally droops to close the slag discharge pipe 3. The hinged baffle 8 can prevent the residue from re-entering the slag discharge pipe 3 when the pressing plate 10 is pressed down.

[0016] The pressing plate 10 is driven to move up and down by the hydraulic rod 11 on the upper part of the extruder 4. A plurality of drainage holes 14 are provided at the lower part of the outer wall of the extruder 4. The bottom of the extruder 4 is open. A bottom plate 12 is provided at the bottom of the extruder 4. The bottom plate 12 closes the bottom opening. The lower side of the bottom plate 12 is connected and fixed to the hydraulic push rod 13. A water collecting trough 15 is provided below the extruder 4. The water discharged from the drainage hole 14 can fall into the water collecting trough 15.

[0017] When the hydraulic rod 11 drives the pressing plate 10 to press down, the bottom plate 12 is supported by the hydraulic push rod 13 to close the bottom opening of the extruder 4, so that the extruder 4 forms an extrusion groove. During the downward pressing process of the pressing plate 10, the liquid in the residue will be discharged from the drain port 14 and flow into the sump 15. In order to prevent the liquid from splashing during extrusion, a water baffle 16 is provided on the outside of the drain port 14. The water baffle 16 surrounds the outside of the drain port 14, and its lower part is open.

[0018] The drainage ports 14 are evenly distributed around the extruder 4. The drainage ports 14 are vertical openings. The vertical openings are not only convenient for drainage, but also more convenient for cleaning than circular hole drainage.
